An illustrative embodiment describes a method and apparatus for carrying optical-based digital information over millimeter wave radio frequency (RF) waves and broadband electrical power line systems. The illustrative embodiment transmission procedure has the merit of leveraging pre-existent low voltage residential wiring on the premises of an end user device to efficiently provide broadband access. Moreover, in a particular illustrative embodiment direct conversion of an optical signal to a millimeter-wave RF signal minimizes conversion losses, and facilitates digital communications at higher speeds. For instance, in a particular illustrative embodiment a uni-traveling carrier photodiode may be used in the RF transmitter. In another particular illustrative embodiment are electro-optic sampling techniques may be used in the RF receiver. After reception at the premises or other location of a customer premises equipment or end user device, the information bearing RF signal is carried over a power line modem and placed onto the distribution low voltage electrical wiring at premises associated with an end user device. A user then communicates with the digital network by attaching one or more terminal end user devices to a matching power line modem and connecting an end user device anywhere onto the distribution wiring.

Multiple power line modems may be provided and used for sharing the available bandwidth, at which digital data is delivered at broadband optical speeds. A particular illustrative embodiment has the advantage of facilitating mass broadband communication techniques with the use of modern-day photonic techniques. In another particular illustrative embodiment WiFi equipment may also be added at the end user device location or used in place of the RF transmitter for enhanced digital data delivery and communications experience. The present disclosure targets the frequency band 30 GHz to 300 GHz and delivers Gigabit Ethernet speeds in excess of 1000 BASE-SX (1.25 Gbit/s), thus supporting various forms of bandwidth-sharing. The high speeds links will support converged services (VOIP, data, and full motion video) with minimal degradation to the combined converged service applications. The use of modern-day photonic techniques for transmission and reception also enables the use of the envelope of the transmission signal for passing data, while the phase of the transmission signal may be used for link management. In addition, the phase may be used for enhanced power output whenever link degradation occurs.

The illustrative embodiment of this disclosure enables mass and efficient delivery of converged packet services over high speed networks. When broadcast cable is used for these services, bandwidth delivery degrades with increasing number of users. This is because broadcast bandwidth is shared by all members of a broadcast reception audience. Every new added application is sent to every member of the broadcast audience even if it is inserted into the broadcast stream for only a few on only member audience. Switched packet broadband networks such as the triple play IPTV, VoIP and data network provide to distributed internet protocol data over a network of routers and servers, however, sends only the IP packet data intended for a particular audience member to that audience member rather than sending everything to everyone in the broadcast audience as in the broadcast communications model. IP data streams can be unicast and multicast to specific audience members only. The delivery of switched packet broadband services over digital subscriber lines (DSL) requires the presence of copper loops, which may be a problem for competitive local exchange carriers (CLECs). The use of the low voltage residential power distribution network allows rapid broadband access in a particular illustrative embodiment. The use of millimeter wave communications also presents a reusable or stackable technology. Since the RF communication links are short, interference is not a problem allowing proximate multiple instances, each in a particular local region close to an RF transmitter and proximate other local regions without RF interference between instances or local regions are.

A particular illustrative embodiment combines the use of photonic techniques and millimeter wave communications for high speed delivery of information, which can also be combined with signaling over the low voltage residential power grid for rapid deployment.

Photonic techniques supports broadband signaling, enabling high speed data to be delivered with limited or no degradation of video applications and also enable substantial bandwidth flexibility.

As shown in FIG. 1, in an illustrative embodiment a triple play IP network 102 which may include an internet protocol television (IPTV) system, a voice over internet protocol (VoIP) system, and a data delivery and internet service provider system sending digital data over fiber optic cables 103 to a network node such as a digital service line aggregate or multiplexer (DSLAM) 104. Each triple play network includes processors 142, memory 143, database 144, servers 141 and routers 145 which distribute internet protocol data to network nodes 104. The network 102 can be any source of digital data and is not limited to the triple play IP network shown in an illustrative embodiment. The network node is located adjacent to a RF converter transmitter 106 which converts the broadband data from the triple play IP network to an RF signal 108 in the range of 30-300 GHZ in an illustrative embodiment. The RF signal 108 is received by an RF receiver 110 in an illustrative embodiment at an electrical power pole 115 located adjacent a residence 120. The residence is associated with an end user device 122. The RF receiver 110 communicates converted digital data converted from the RF received signal to an electric power modem 112. The electric power modem 112 feeds the converted optical signal to the electric power line 114 which runs from the power pole distribution transformer 116 to the residence 120.

An electric power modem 118 is located at the residence 120 and receives the digital data and power from power line 114. The power modem 118 then extracts the digital data signal from the power line and communicates the extracted digital data to IP device 122. IP device 122 is plugged into the internal electrical line 119 upon which the power modem 118 communicates the data over the internal electrical wiring 119 to the IP device 122.

Also shown in FIG. 1 are adjacent residences 121 and 123 which contain power modems 131, 133 in which each power modem may operate within a different and unique separate frequency band thus the RF signal can be frequency multiplexed such that only a portion of the bandwidth of the RF signal from the receiver is used for each residence and each residence can share the bandwidth of the output RF signal from the RF receiver. Also shown in FIG. 1 is the electrical power source power generating plant 130 which transmits voltage at a high transmission power voltage to distribution substation 132 which steps down the transmission power voltage to a medium distribution voltage. The distribution substation transmits the transformed transmission power voltage at the medium distribution voltage power to local power poles 115 containing residential transformers 116 which reduce the distribution voltage to the low residential voltage level which is delivered to and used inside of the house on the internal electrical wiring at 220/110V. In another particular illustrative embodiment, available bandwidth is the bandwidth available at modem 112, in which modem 112 acts as a data source that shares its available bandwidth with modems 118, 131 and 133. Each of the modems can be identified by their respective machine address code (MAC) addresses. The individual devices that are attached to the modems with in the residences can be differentiated based on their individual internet protocol (IP) addresses.

The first local region 111 and a second local region 113 and other local regions 3-N can be served without RF interference between local regions as the RF signal transmitter 106 in each local region is chosen to deliver a signal having frequency and power so that the RF signal attenuates rapidly with distance from the RF transmitter 106. Thus a particular RF transmitter is effective only in its local region so that it doesn't interfere with a signal from another RF transmitter in another local region. RF transmitter can be set a different frequency bands in proximate regions to reduce interference.

Turning now to FIG. 2 in another particular illustrative embodiment the triple play network digital data signal is routed via fiber optic cable to a network node or DSLAM 104 where RF converter 106 converts the fiber optic data signal 103 to a 30-300 GHZ RF data signal 108 which is transmitted directly to a RF receiver 110 at a residence 120. The RF receiver 110 converts the received RF signal to a converted digital signal and the power modem 118 places the converted digital signal on the internal electric low voltage power wiring 119. The internal power wiring delivers the data signal to internal power modem 118 which takes the digital data off of the internal power wiring and further communicates the digital data to end user devices such as IP device 122.

Also as shown in FIG. 2 are houses 121 and 123 which contain RF receivers 108, 110 2-N and associated power modems 118 wherein each receiver can be designed to receive in a different frequency band so that frequency division multiplexing can be used at the RF converter transmitter 106 to frequency multiplex or divide signals into different frequency bands intended for different residences or houses. The different frequency bands can be used so that each house receives at different frequency band and the bandwidth can be shared between residences. This way the triple play IP network and DSLAM node can assign particular multicast and unicast digital stream to particular frequency bands associated with one or more particular end user devices.

Each of the separate signals can also be separately encrypted such that only a house for which an encrypted data signal was intended can decrypt the data signal. In the case of encryption, the data signals can all be the same frequency or on separate frequencies such that frequency division multiplexing and encryption can be used together or separately.

Turning now to FIG. 3, as shown in FIG. 3 in another particular illustrative embodiment a triple play IP network transmits a data signal on broadband speeds to a triple play IP network node such as a DSLAM. The DLSAM 104 transmits the IP digital data signal to a power modem 112 which places the digital data signal on a power line at the higher distribution voltage before it is stepped down to residential voltage (110/220 V) at the distribution voltage substation. When the distribution voltage power containing the data signal is received at a residential power pole 115 to be stepped down to residential 110/220 by residential transformers 116, the data signal on the distribution line is received by a power modem 118 and converted to an RF signal by a power converter and transmitter 106.

The RF receiver 110 receives the RF signal generated by power converter 106 and communicates the RF signal to the power modem 128 which places the data signal on the residential power line 114. The RF transmitter 106 and RF receiver 110 transfers the broadband digital signal across the residential transformer. The residential power line 114 containing the broadband data signal supplies power and data to the residences 120,121 and 123. Each residence includes an internal power modem 130, 131 and 132 that receives the power and data signal supplied from the residential power line 114 and converts the data transferred to the internal wiring 119 to a data signal which is then communicated to and end user device such as IP device 122. The end user device or IP device can be a personal computer or set top box or any other Internet protocol or digital data device capable of receiving a digital data signal. Digital data signals from the end user device or IP device which may comprise any end user device capable of receiving a digital data signal can also be transmitted back to the triple play IP network by sending a data signal in reverse direction retracing the path of the data in reverse back to the triple play IP network or another communication network. Wireless fidelity (WWI) or another wireless communication protocol can be used to distribute the data signal within or near a residence to end user devices.

Turning now to FIG. 4, in a particular illustrative embodiment an RF converter transmitter 106 receives an optical digital data signal 103 on a fiber optic cable from a triple play network node. In one particular illustrative embodiment, the RF converter transmitter contains a uni-traveling carrier photodiode 402 which converts the input optical digital data signal to an electrical signal which is coupled into the RF antennae or wave guide 404 and transmitted as a 30-300 GHZ RF signal 405. The RF receiver 110 further comprises an electro optical sampling circuit 410 which converts the received converted RF signal 405 to a digital output signal 408.

Nagatsua, Institute of Physics Publishing, Measurement Science and Technology, Vol. 13, pp. 1655-1663 (2002), which is incorporated herein by reference in its entirety.

Nagatsuma, NTT Review, Vol. 14, No. 6, November 2002, pp. 42-48, which is hereby incorporated by reference in its entirety.

There are numerous ways that data can be modulated on a millimeter-wave (MMW) and sent over a link. In another particular illustrative embodiment, the digital data is intensity-modulated on the optical signal before the optical signal reaches the uni-traveling carrier photodiode for MMW conversion. In this case, a harmonic mixer can be used to demodulate the transmitted MMW signal and a signal phase might not be available for secondary link control. In another particular embodiment, a the MMW signal may carry both amplitude and phase information over the transmission link and electro-optic sampling can is used for demodulation. In this case, the amplitude information is used for sending digital data and the phase information used for link control.

An optical signal containing broadband digital data is received as shown at block 502. The optical signal is converted to a first radio frequency signal as shown at block 504.

In another particular embodiment, the first subset of the band of frequencies and the second subset of the band of frequencies do not overlap as shown at block 512.
